Van Horn, who has missed three straight games with a sprained left ankle and contusion on his left calf, may play, according to coach Terry Porter. Injured against the Bulls last Friday, Van Horn has averaged 17.9 points and 6.9 rebounds in 19 games since being traded to Milwaukee.

Milwaukee, competing for the fourth seed in the Eastern Conference and home-court advantage in the first round, is coming off a 111-78 loss to the Indiana Pacers on Wednesday.

The Bucks came into the game fourth in the NBA in scoring, averaging 97.2 points, but were completely shut down by one of the best defensive teams in the league.

All-Star guard Michael Redd, Milwaukee’s leading scorer, shot 3 of 17 and finished with a season-low six points. He had scored in double figures in 48 straight games.

Cleveland lost 126-109 to the Dallas Mavericks on Tuesday. LeBron James finished with 28 points, six assists and five rebounds as the Cavaliers lost their second straight and sixth in seven games.

It also clinched a losing record for the Cavaliers, who are 1 1/2 games behind the Boston Celtics for the final playoff spot in the East.

“We know we need wins,” James said. “We’ve overachieved this year. Not being in the playoffs would hurt, but we’re not going to hang our heads if we don’t make it. We’ve got to keep playing the same game we’ve been playing all year.”
